Question

1. what is voltage? (1 point)

it is the flow of an electric charge in only one direction.
it is the sum of the electrical potential energy between two places in an electric field.
it is the flow of an electric charge that regularly reverses direction.
it is the difference in electrical potential energy between two places in an electric field.

Explanation:

Voltage is defined as the difference in electrical potential energy between two points in an electric field. Let's analyze each option:

• "It is the flow of an electric charge in only one direction" describes direct current (DC), not voltage.
• "It is the sum of the electrical potential energy between two places in an electric field" is incorrect as it's a difference, not a sum.
• "It is the flow of an electric charge that regularly reverses direction" describes alternating current (AC), not voltage.
• "It is the difference in electrical potential energy between two places in an electric field" correctly defines voltage.

Answer:

It is the difference in electrical potential energy between two places in an electric field.
